PE A-THRE SHER.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed March 25. 1907. Serial No. 364.446.

To all whom it may concern:

Be it known that I, EMMETT W. JONES, a citizen of the United States, residing at Burts, in the county of Sussex, State of Virginia, have invented certain new and useful Improvements in PeaThreshers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in machines for threshing or separating peas, and has for its object to provide a novel construction, combination and arrangement of parts.

The details of the invention will appear in the course of the following description, in which reference is had to the accompanying drawings forming a art of this specification, like characters of reference designating similar parts throughout the severa wherein:

Figure 1 is a side elevation of a machine constructed in accordance with my invention. Fig. 2 is an elevation looking at the opposite side from that shown in Fig. 1. Fig. 3 is a central longitudinal sectional view thereof. Fig. 4 is a section on the line 44 of Fig. 3. Fig. 5 is a longitudinal section of a stemming mechanism. Fig. 6 is a detail perspective view of operative connections for vibrating the screening mechanism.

The invention in its practical embodiment comprises an open frame 1, from which the 0 erative elements are suspended. A drive s aft 2, is journaled in bearings provided upon one of the rear bars of said frame, the shaft 2 carrying a power pulley 3 and a trans mission pulley 4. A shaft 5 is journaled forwardly of the shaft 2. -The shaft 5 carries a pulley 6, over whicha chain or belt 7 is trained, the'belt 7 being connected with a suitable motor. The shaft 5 likewise carries a cylindrical drum 8 having its periphery provided with closely associated radially extending ins 9. A hood 10 of concave cross sectiona curvature is fixed to the frame 1 above the drum 8 in spaced relation thereto. The hood 10 is concentric to the drum 8, and is provided on its inner surface with pins 11, arranged in staggered relation with pins 9 in order to ermit of the passage of sald pins 9 thereby uring the rotation of the drum 8. Said drum together with the hood 10 constitutes a threshing mechanism and is disposed views,

adjacent to a feed table 12, mounted at the rear of the frames 1, and arranged above an operator stand or platform 13. Adjacent the front and rear ends of the frame are parallel transverse shafts 14, over which a conveyer belt 15 is trained, the latter being disposed below the drum 8. The forward shaft 14 carries at one side thereof a pulley 16, and the shaft 5 carries at the end adjacent to the pulley 16 a pulley 17. A transmission belt 18 is trained over these pulleys and serves to drive the former from the latter.

Pivotally depending from the top side bars of the frame 1, are links 19, which may be either rods or wire, and which are arranged in pairs at each side of said frame. The links 19 in this disposition serve as supports for a rod 20. The rod 20 is provided with forwardly extending closely associated fingers 21, approximately horizontal and affording a sieve or screen for the peas and hulls fed thereto from the belt 15. It is preferred that the fingers 21 be of substantial L-shape, in order that the hulls may work through spaces between the perpendicular portions 22 of said fingers to a suitable inclined plate 23, disposed rearwardly thereof, and in order that the peas and fine extraneous matter, may work through the spaces between the horizontal portions 24 of the fingers 21, to a suitable spout 25 provided therefor. The plate 23 passes beneath the mouth of a fan blower 26 of conventional form, the power shaft 27 of which carries at one-end a pulley 28. The shaft 5 is provided in addition to the pulley 17 with a pulley 29, and a bolt 30 is trained over the pulleys 28 and 29 and serves to drive the former fromthe latter. The spout 25 communicates with a stemming mechanism 31 which comprises a casing 32 having an open upper end communicating with the spout 25 mounted on a suitable support. A shaft 33 is projected horizontally through the casing 32, and carries within said casing vertically arranged saws 34, working between bars or plates 34*, projecting from the inner surface of the casing. The shaft 33, at its projecting end is provided with a pulley 38. A belt 39 is trained over the pulleys 4 and 38, and affords an operative connection therebetween.

At one side of the conveyer belt 15, a vertical rock shaft 40 is mounted, which is provided adjacent its upper and lower ends with respective oppositely extending upper and lower arms 41 and 42. The shaft 5 is provided with a crank arm 43, and a pitman or link 44 affords connection between the crank arm 43 and the upper arm 41 of the shaft 40. In like manner the lower arm 42, of said shaft has connection with one end of the rod 20, and affords an operative transmission element whereby the shaft 40 by its rocking movement, vibrates said rod 20, the links or hangers 19 of course rocking to and fro during such vibratory action.

In practical use, the peas are introduced into the space between the drum 8, and the hood 10, and the hulls are stripped by means of the pins 9 and 11, the former moving with relation to the latter. The hulls and peas are then shed promiscuously upon the belt 15 and conveyed thereby to the sieve or screen constituted by the fingers 20. Owing to the vibratory action of these fingers, the hulls will work therethrough upon the plate 23 in the manner previously set forth, and the peas and the fine extraneous matter will work through the spout 25. From the latter they pass into the casing 32, and the stems and dirt are separated by the rapidly revolving saws 34 of the shaft 33, the peas being then discharged through a suitable spout 46 to any desired receptacle provided therefor.

From the foregoing description it will be seen that simple and efficient means are provided for accomplishing the object of the invention, while the elements herein shown and described are well adapted to serve the purposes for which they are intended, it is obvious that various minor changes may be made in the proportions, shape and arrangement of the several parts without departing from the spirit and scope of my invention as defined in the appended claims.

What is claimed, is:

1. A machine of the type set forth, comprising threshing mechanism, an endless apron leading therefrom, a screening mechanism located adjacent the discharge end of said conveyer and comprising a vibratory rod provided with closely associated parallel fingers having perpendicular portions and horizontal portions projecting outwardly from the lower ends of said perpendicular portions, means for vibrating said rod, an inclined plate disposed inwardly of said perpendicular portions to receive the material working through the spaces therebetween and an angularly disposed transverse inclined spout arranged beneath said horizontal portions to receive the material working through the spaces therebetween.

2. A machine of the type set forth, comprising threshing mechanism, an endless apron leading therefrom, a screening mechanism located adjacent the discharge end of said conveyer and comprising a vibratory rod provided with closely associated fingers having perpendicular portions and horizontal portions, an inclined stationary plate disposed to receive the material Working through the spaces between said perpendicular portions, an angularly disposed station ary spout arranged to receive the material working through the spaces between said horizontal portions, and means for vibrating said rod comprising a vertical rock shaft having upper and lower angularly disposed arms, the lower arm being connected to said vibratory rod, and operating mechanism connected to the upper arm of said shaft.

In testimony whereof, I affix my signature, in presence of two witnesses.
